Abstract
Abstract Masny anomalous physical properties have been observed in the high-Tc cuprate superconductors for the last decade. These includet (1) the unconventional isotope effects on the supercarrier mass, on the charge-stripe formation temperature, on the spin-glass freezing temperature and on the antiferromagnetic ordering temperature; (2) the exotic pairing symmetry shown by many bulk-sensitive experiments; (3) the magnetic resonance peak in the superconducting state revealed by inelastic neutron scattering; (4) the peak, dip and hump features seen in angle-resolved photoemission spectroscopy and in tunnelling spectra; (5) the strong-coupling features in optical and tunnelling data; (6) the pseudogap in the normal state of underdoped cuprates and (7) the unusually large supercarrier mass anisotropy and its novel doping dependence. We review these important experimental results, which can place crucial constraints on the physics of cuprates. The conclusion is that high-Tc superconductivity in cuprates is a cooperative phenomenon between the strong electron-electron correlation and strong electron-phonon coupling.
